Ruy Lopez Steinitz Defense Discovered Attack Chess Puzzles

In the Ruy Lopez Steinitz Defense, a discovered attack happens when one piece moves and uncovers a stronger line from a rook, bishop, or queen onto a target. The defining feature is the Steinitz structure after 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6, where tension around the bishop pair and central pieces can create tactical lines along the e-file, c-file, or long diagonals. For an intermediate player, this motif usually appears when a pinned or blocking piece steps aside and suddenly exposes an attack on the king, queen, or an undefended piece.
